There are assortments of games that will be played during your Knockerball experience.  Players will experience Knocker Soccer as the primary game.  However, most or all of the following games will be played depending on the player requests and/or referee choice based on each group of Knockerball participants.

King of the Ring:
You’ve heard of “King of the Hill”, well, how about you put on a Bubble Ball and be the last person standing. It’s bound to get physical.

There’s just two of you in a ring… who will be left inside?

Red Rover:

The game is played between two lines of players. The game starts when the first team calls a player out, using a line like “Red rover, red rover, send [name of player on opposite team] right over”.

The immediate goal for the person called is to run to the other line and break through the team’s Knockerball wall.  If the person called fails to break through, this player joins the opposing team. However, if the player successfully breaks through the wall, this player may select either of the two “links” broken by the successful run, and take them to join their team. The teams take turns.

When only one player is left on a team, they also must try and break through a link. If they do not succeed, the opposing team wins.

Human Bowling:
Why would you go the bowling alley when you can have your friends act as the pins and you be the ball?!! Can you get a strike?


All matches must be played according to the referee’s interpretation of the rules.

  • Each game is comprised of four quarters that are five minutes long with five minute breaks in between.
  • Kick-Off – the ball will be placed in the center of the field, teams line up along their goal line. When the whistle blows teams may run to the ball for possession. This will occur every time a goal is scored.
  • Kick-Ins – all kick-ins from the side line must be kicked in by the opposite team that kicked it out. There must be a 5 yard gap from where the ball is kicked in.
  • Free kick – awarded at the discretion of the referee. The opposition must be 5 yards away from where the kick is being taken. All Free Kicks including Kick-Ins must touch another player on the kicking team before scoring.
  • No Off sides.
  • Balls in Bubbles – if the ball lands in a bubble, play will stop and the ball dropped with one member from each team.
  • Corner kicks will be played as per normal.
